Police are asking the public for their assistance in locating an 11-year-old foster child who went missing Monday morning after being dropped off at an elementary school in San Leandro. The missing juvenile, Myles Oliverez, was dropped off at Madison Elementary School at 14571 Juniper St. on Monday at 7:25 a.m., police said.

He failed to return to his foster home at the end of the school day, police said.

There are no indications of foul play at this time, police said.
